[asterisk-users] SIP port 5060 closed - how do I open it?

[Zaheer K. Master]

I ran an nmap scan on my server and got the following result:
Starting Nmap 4.23RC3 ( http://insecure.org ) at 2007-11-28 10:29 Eastern
Standard Time
Interesting ports on ool-4b7fda52.static.optonline.net (75.127.218.82):
PORT     STATE         SERVICE
5060/udp open|filtered sip

So I'm pretty sure that the SIP service is up and running on the port - does
anyone know what the "filtered" statement means? Thanks again!

Regards,
Zaheer
